I'm surprised to see so many people using nicotine replacement therapy. I don't think it's a very effective way of quitting. Many people are saying they have 'quit' smoking but they still have a nice steady stream of nicotine in their blood stream. I'm now on day 29 quitting cold turkey (with the help of Allen Carr) and I don't crave nicotine in the slightest. It only really takes a few days for the nicotine to leave your body, after that it's all mental. At this point in time the only time I even think about cigarettes is when I'm on here, and have about as much desire to smoke one as I do to throw myself down a pair of stairs.
